A further object of the invention is to provide an air pump for dischfarginga current of airinto the carbureter andmeans for; connections be-,. tween said meansand thegasometer for automatically controlling the operation of the air pump and automatically interrupting or opening the liquid controlling means;

The invention consists. in the combination of a gasometer and acarbureter, withmeans for supplying a substantially constant charge of volatile liquid of uniform richness e generating chamber, and means for of the liquid into chamber may be of suitand diameter, and is vprovided with a multiplicity conical drain I shelves 16, with upon which is securelymounted conical deof somewhat less diameter than they diameter of the chamber I and the construction and combination of.

which is suitably with a spindle valve 23 mounted in the chamber 10 and has an upwardly projecting stem upon which is mounted a collar 24 bearing a spring 26 reacting against a loose collar 27, above which is disposed a lever 23 operable by a means hereinafter to be described, close theoutlet at the valve seat 22 above the regulator valve 20. from chamber 21, through ports 22 formed in a tube 22 which acts as a guide for the stem of valve 23.

Totthe end of maintaining the desired quantity of oil in the head tank 21 at a given level and at the same time not cause its overflow to the oil pipe 12 of the chamber 10, there ismounted in the head chamber 21 a float 30 connected to a lever 31 of a valve 32 opening outwardly from the tank 21 and closing upon a seat 33 when the float 30 rises, and thus shutting off incoming oil from a supply pipe 34: which is connected to 35; it being n11 derstood that the drum 35 while here shown as arranged ti'on with relation to the apparatus, 'may be arranged overhead and at a suitable disposition so long as sufhcient pressure can be obtained to feed the liquid asrapidly as desired to the carbureter. v The top of the chamber 10 may have a partition as shown between float 30 and cowl 11L 1 Since the present arrangement source of supply or drum or below the level of the head tank 21, suitshows the able means are shown as an air pipe 36 by which air under pressure is conveyed to the drum from a compresser 37 of suitable type which may derive power from the motor 38 of any suitable character. I The motor 33 is also utilized to drive a suitable air feed mechanism here shown. asa blower 39 having a relief valve to automatically operable to open when a normal or desired pressure is exceeded. The blower 39 has a discharge tube 41 which discharges air into the lower end of the carbureter chamber 15, rising in circuitous paths upwardly through the drum as it passesthe several superposed end of the free liquid communrto open and Gasolene p asses undergroundvor in a safe posh 35 as underground the air the downwardly turned cowl 11 which tends to throw down the heavier contents of moisture in the rising column of air which has been enriched by the liquid, and passes thence from the chamber 10 through the pipe 5 intothe gasometer 2. j

The automatic charging ofthe gasometer 2 in proportion to the volume of carbureted air discharged therefrom is accomplished by means controlled by the rise and fall of the gasometer 2, whichmeans operate to cut out the motor 38, thus stopping the operation of the blower 39 whichi'orces air through the carbureting chamber 15, and also stopping the compressor 37 which generates pressure in the reservoir drum 35 to lift the oil to the head chamber 21. This means for auto matically throwing out the blower and compressor, andalso for cutting oli the feed of oil from the head tank 21, comprises a connecting device here shown as a cable 15 connected tothe tank and passing through suit able guide sheaves 46, the lower end of the cable being provided with a rod or other suitable member 4L7, weighted at its lower end 18 and carrying stop collars 19 adjustably mounted and spaced on the rod at. These collars 49 are adapted to move and throw a lever 50which is mounted upon a pivot-shaft 51, the lever having angularly spaced lugs 52 adapted to engage a trip device or weight 53 loosely mounted on the spindle 51, the device 53 having lugs 5a engageable with adjacent portions of a walking beam or actuator 55, pivoted upon the shaft 51, one end of the actuator 55 being connectedby alink 56 to a lever 57, pivoted at 58 upon a su'table support or portion of a frame supporting the head tank 21, the lever 57 being connected at its opposite end to a link 59,'which in turn is joined to a throttle valve member 60 for controlling the motor 38, of whatever type it may be. The opposite end lot the actuating lever 55 on. the shaft "51 is connected to a link (31, the upper end of which is joined to the lever 28 which engages the collars 2'? on the cut-out needle valve 23. a

The operation of the automatic cut-out mechanism is as follows? When the ometer rises toward its highest position the cable or connection 15 permits the rod portion at to descend, so that the upper collar 49 will engage 50 and gradually swing this downwardly; one of the stops 52 on the lever the upwardly inclined lever 50 will en- I the carbureting chamber shaft 51 and engage the opposite lug the lever 50,. the gravitatingmotion of the engaging at one of its shoulders fil the opposite side of the actuating lever 55, so that it will pull down the link 61, and this downward movementebeing transmitted through the lever 28 will press the needle: valve 23 down to cut off the feed to the regulating valve 20,thus stopping the feed of oil to the carbureting chamber 15; as the valve actuating link 61 moves down the link 56 will be drawn up and rock the lever 57, W ich. in turn Will through means of the link 59 throw the valve 60 to cut out the motor 38, thus stopping the opera ion of the 'blow'e pressor 87. As the I from the buoyant gasometer 2, the latter will gravitate downwardly andv through means of the connection 45 will lift the rod 417,, so that the l e brought into iis constant openmg, operative and inoperative relationof the parts provide for a continuous supply of the mixture in the gasometer 2.

The richness of the mixture can be varied by thequan'tity of oil passing through the' feed chamber feed pipe 34, thus malntaining a substan-- tially constant level and tity of oil in the feed chamber 21. By maintaining a free circulation of oil between the tank 13, and the feed tank 21 the excess will flow freely from the feed tank 21 through the overflow pipe 12 to the tank 13.

ratus involving features designed to reduce the element of danger by explosion to a minimum, by providing a direct feed chamstant uniformity as 39 and the air com-g mixture is exhausted ower collar 49 thereon will g automatically her which Will contain a relatively small quantity'of oil. Secondly, the apparatus is designed to produce a mixture of substantially uniform richness by reason of the supply of oil from the chamber 21 of conto grade; and, I have devised an apparatus which ple in construction, automatically operable, and in which the chamber 15 is free from moving elements, thereby avoiding any chance of other untoward causes.

Having thus described my invention what I claim and desire to secure by Letters Patcut, is:
